DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 1 to 7 for the perspective views of the present invention and the schematic views of the preferred embodiments of the present invention respectively, a packaging cardboard frame with a buffer mechanism 1 comprises a hollow structure unit 2 or a solid structure unit 3, made by continuously pressing and folding a cardboard, and the cardboard includes a plurality of folding lines 5 formed thereon and provided for a machine to continuously press and fold the cardboard along the folding lines 5 to stack the cardboard into the solid structure unit 3, or form a hollow structure 2 at the center position in any two of the solid structure units 3, and the packaging cardboard frame with a buffer mechanism 1 further comprises at least one notch 6 for latching or embedding the packaging cardboard frame with a buffer mechanism 1, and a cushion material 4 is embedded into the center position of the hollow structure unit 2 to produce elasticity, wherein the cushion material 4 can be a plastic frame, an air pad, a polylon or EPE foam material, such that the packaging cardboard frame can have the supporting and buffering effects concurrently.

Wherein, the notch 6 is formed on the hollow structure unit 2 or the solid structure unit 3, and the hollow structure unit 2 or the solid structure unit 3 can be latched or embedded, and the notch 6 can be manufactured by the following two methods:

(1) The position of the notch is measured and estimated first, before the machine continuously presses and folds the cardboard, and a cutting tool is used for cutting and forming the notch.

(2) After the machine continuously presses and folds the cardboard into the hollow structure unit 2 or the solid structure unit 3, the notch 6 is cut and formed directly from the hollow structure unit 2 or the solid structure unit 3. When the machine presses and folds the cardboard, glue can be sprayed or coated to enhance the strength of the folded packaging cardboard frame with a buffer mechanism 1.

In addition, the notch 6 is provided for latching or embedding the hollow structure unit 2 or the solid structure unit 3 in a horizontal direction or a perpendicular direction to form a three-dimensional column structure, wherein the notch 6 can be rectangular, L-shaped, O-shaped or cross-shaped. A groove is formed at the same position of the folding line 5 to facilitate pressing and folding the cardboard to improve the seal level of the pressed and folded cardboard. The hollow structure unit 2 or the solid structure unit 3 can be an I-shaped column structure, an L-shaped column structure, or an L-shaped column structure with a recession formed at the middle of the L-shaped column structure. Both sides of the I-shaped column structure or I-shaped column structure can be pressed and folded continuously and stacked to form a more secured supporting structure, and a spring, an air column, or a polylon cushion material 4 is stuffed at the weaker position at the middle of the packaging cardboard frame.

In summation of the description above, the packaging cardboard frame with a buffer mechanism 1 of the present invention can overcome the problems of the conventional way of manually cutting, pressing and folding the cardboard that cannot complete the finished goods by the machines on the production line directly.
